FPGA-BASED TENSOR COMPRESSIVE SENSING RECONSTRUCTION PROCESSOR FOR TERAHERTZ SINGLE-PIXEL IMAGING SYSTEMS

Terahertz (THz) imaging system has great potentials for material identification, security screening, circuit inspection, bioinformatics and bio-imaging because it can penetrate various non-metallic materials and inhibits unique spectral fingerprints of a great variety of optically opaque materials in our daily lives.However, THz emitters and detect

The Talbot self-imaging effect is mostly present in the forms of space or time, or in the frequency domain by the Fourier duality.Here, we disclose a new spectral Talbot effect arising in optical orbital angular momentum (OAM) modes.The effect occurs Garden in the context of petal-like beams, which are typically constructed from a number of in-phas
